Description

461 582 Ändamålet uppnås genom att vattnet, som innehåller fint material, på sin väg tillbaka till inloppsänden pà fraktioneringstanken, tillföres sanden som skall passera sállet, varigenom nödvändig tillförsel av nytt vatten inskränkes till att ersätta det vatten, som följer med den fraktionerade sanden som uttages ur anlägg- ningen. The purpose is achieved by supplying the water containing fine material on its way back to the inlet end of the fractionation tank with the sand which is to pass through the sieve, whereby the necessary supply of new water is reduced to replace the water which accompanies the fractionated sand taken out. out of the facility.

Ett utföringsexempel enligt uppfinningen visas schematiskt på ritningen som sett från sidan visar en anläggning för framställ- ning av fraktionerad sand.An embodiment according to the invention is shown schematically in the drawing which, seen from the side, shows a plant for the production of fractionated sand.

Pâ ritningen betecknar hänvisningsbeteckningen l ett transport- band som via en tratt 2 leder sand till ett sàll 3. Sållet 3 är anordnat att kunna röras sà att större partiklar, företrädesvis singel, som inte släpps igenom sállet 3, leds längs detta till ett transportband 4 som för bort singeln. Sand som passerar sàllet 3 tillsättes stora mängder vatten via dysor 5.In the drawing, the reference numeral 1 denotes a conveyor belt which, via a funnel 2, leads sand to a sieve 3. The sieve 3 is arranged to be able to be moved so that larger particles, preferably shingle, which are not passed through the sieve 3, are guided along it to a conveyor belt 4 which removes the single. Sand passing through the sieve 3 is added to large amounts of water via nozzles 5.

Sand/vatten-blandningen ledes via ett inloppsrör 6 till en vattenfylld tank 7. Beroende pà sandkornens storlek, kommer dessa att avsätta sig längs tankens 7 botten 8 i riktning fràn inlopps- röret 6. I tankens 7 botten 8 är anordnat ett antal ventiler (ej visade) varigenom sandkornen med olika storlekar kan ledas till ett gemensamt utloppsrör 9. Beroende av ventilernas öppningstid och vilka ventiler som öppnas, kommer man att kunna framställa sand med en pà förhand bestämd karaktär, s.k. fraktionerad sand.The sand / water mixture is led via an inlet pipe 6 to a water-filled tank 7. Depending on the size of the sand grains, these will settle along the bottom 8 of the tank 7 in the direction of the inlet pipe 6. A number of valves are arranged in the bottom 8 of the tank 7 ( not shown) whereby the sand grains of different sizes can be led to a common outlet pipe 9. Depending on the opening time of the valves and which valves are opened, it will be possible to produce sand with a predetermined character, so-called fractionated sand.

För att sandmassorna som leds in i tanken 7 skall få en relativt jämn spridning längs tankens 7 botten 8, är anordnat en pump 10 som via rör ll pumpar vatten upp genom dysor 12. I tanken 7 finns också anordnat ett överloppsrör 13 varigenom vatten kan ledas bort t.ex. via en sedimenteringsbassäng (ej visad). För att det fina materialet i sanden ej skall sköljas bort tillsammans med överloppsvattnet, är i anslutning till tanken 7 anordnat en pump 14 som via ett rör 15 leder vatten frán tanken 7 till tratten 2.In order for the sand masses which are led into the tank 7 to have a relatively even spread along the bottom 8 of the tank 7, a pump 10 is arranged which, via pipe 11, pumps water up through nozzles 12. In the tank 7 there is also arranged an overflow pipe 13 through which water can be led. away e.g. via a sedimentation basin (not shown). In order that the fine material in the sand is not to be washed away together with the overflow water, a pump 14 is arranged in connection with the tank 7, which pumps water from the tank 7 to the funnel 2 via a pipe 15.

Inloppsöppningen till röret 15 ligger lägre än inlopps- öppningen till överloppsröret 13, och beroende av pumpens 14 kapacitet kommer önskad vattenmängd att kunna recirkuleras.The inlet opening to the pipe 15 is lower than the inlet opening to the overflow pipe 13, and depending on the capacity of the pump 14, the desired amount of water will be able to be recycled.

Genom att vatten som recirkuleras innehåller det fina materialet, kommer vattnet stadigt att bli mer mättat av älv 461 382 sådant stoff, vilket självfallet medför att större mängd Flnt material kommer att falla till botten till tanken 7 och kunna föras ut via ventilerna i tankens 7 botten.Because water that is recycled contains the fine material, the water will steadily become more saturated by such a substance, which of course means that a larger amount of Flnt material will fall to the bottom of the tank 7 and can be carried out via the valves in the bottom of the tank 7 .

Genom att recirkulera vattnet, kommer man att kunna reducera vattenbehovet med ca 2/3, samtidigt som man reducerar problemet med överloppsvatten från tanken 7. Om det ar ett önskemål kan vatten som skall recirkuleras, kunna pumpas från överloppsröret 13 eller från en ej visad sedimenteringsbassäng där överloppsröret 13 mynnar ut.By recirculating the water, it will be possible to reduce the water requirement by about 2/3, while reducing the problem of overflow water from the tank 7. If it is desired, water to be recirculated can be pumped from the overflow pipe 13 or from a sedimentation basin (not shown). where the overflow pipe 13 opens out.
